NAME¶

bamrank - insert the rank (line number) of each alignment as an auxiliary field for tag zz

SYNOPSIS¶

bamrank [options]

DESCRIPTION¶

bamrank reads a BAM file from standard input, inserts a new auxiliary field tagged zz containing the rank (line number) of the respective read/alignment and writes the resulting data to standard output as a BAM file. This rank can be used to restore the original order of the file after reordering by using the sequence

bamzztoname | bamsort SO=queryname | bam12strip

The following key=value pairs can be given:

level=<-1|0|1|9|11>: set compression level of the output BAM file. Valid values are

-1:

zlib/gzip default compression level

0:

uncompressed

1:

zlib/gzip level 1 (fast) compression

9:

zlib/gzip level 9 (best) compression

If libmaus has been compiled with support for igzip (see https://software.intel.com/en-us/articles/igzip-a-high-performance-deflate-compressor-with-optimizations-for-genomic-data) then an additional valid value is

11:

igzip compression

verbose=<1>: Valid values are

1:

print progress report on standard error

0:

do not print progress report

tmpfile=<filename>: prefix for temporary files. By default the temporary files are created in the current directory

md5=<0|1>: md5 checksum creation for output file. Valid values are

0:

do not compute checksum. This is the default.

1:

compute checksum. If the md5filename key is set, then the checksum is written to the given file. If md5filename is unset, then no checksum will be computed.

md5filename file name for md5 checksum if md5=1.

index=<0|1>: compute BAM index for output file. Valid values are

0:

do not compute BAM index. This is the default.

1:

compute BAM index. If the indexfilename key is set, then the BAM index is written to the given file. If indexfilename is unset, then no BAM index will be computed.

indexfilename file name for BAM index if index=1.
